' DOORSTOP.

T o-aZZ fwtom it may concern:

Beit knownl that I, MICHAEL J. SASCEN,

a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certa-in new and useful Improvements in .a Doorstop, of which the following is a specification.

My invention relates, to an improved door stop andv has special reference to a stop particularly adapted for outside doors such as garage donors.'

A The obje'ct of. my invention is to provide f a stop of4 very simple andcheap construction preferably comprising but two pieces, a base l5 and a str ut adapted to be a-ttached to the lower part ofthe door.- y. The strut is adapted to be droppedI into an inclined position and to contact with the roadway. The base is formed to provide yielding arms or lugs between which the strut is adapted to be firmly held in non-operative position. The strut may be provided with various forms of ends or shoes for contactingwith the surface of the'roadway.. The roadway withwhich the strut contacts is frequentlymade of cement and I have found it advisable to provide contacting shoes for they lower end of the strut which are adapted to enlarge the contacting surface of the strut and in any case the strut'is provided with a single point or a plurality of teeth or V-shaped edges for contacting with the roadway. My invention will be more readily under- 'stood by reference to the accompanying' drawings forming part of this specification, and which Figure l isa front view of the device shown in position upon a door;

Figure 2 is a side elevation'of the device; 40 Figures 3 and 4 are horizontal sectional views on the lines 3-3 and 4-4 respectively of Figure l;

Figure 5 is a plan view of a bracket blank before the ears are bent up ;A Figure 6 is afra'gmentary side view of a modified formof strut;

Figure 7 is a longitudinal sectional View on the line 7-7 of Figure 6; and

Figure l8 is a view similar to Figure 6 howing a rubber pad for contact withv the oor.

My device comprises a bracket l adapted to be secured to a door near the lower end thereof and a strut member 3 pivotally oon,-

nected to or mounted upon the bracket and adapted to be dropped into the position shown at dotted lines in Figures l and 2 where it acts as a strut to prevent the door from swinging in one direction, or to be raised out of operative position into vertical @0 Vposition and yieldingly heldin inoperative position by suitable ears carried by thel plate l.

Preferably the plate l is made of sheet metal 4and the strut 3 is made from a strip of 65 bar metal. As best shown in Figure 5 the base is first stamped out of sheet metal in somewhat triangular formhaving atl its upper part arms 4 which are adapted to be formed up, as best'shown in Figure 3,l to provide 70 parallel spring arms between which the strut 3 is adapted to be engaged and held as shown in Figure 2. Thebody of the base plate is provided with two portions 5 which are severed at their outer edges 4from the 75 body of the plate and are adapted to be bent up in parallel relation as best shown `in Fig ure 4 to form ears 6 between which one end of the strut 3 is adapted to be received and pivotally secured by a rivet 7. The @0 base is provided with suitable screw holes 8 for receiving fastening `screws by which the base can be secured to the door 2.

The free end ot' the strut 3 may take dit ferent forms or be provided with different Sli kinds of shoes for contact. with the floor or with the roadway, if thedevice is used on a garage door. For the latter use I prefer to provide the lower end 9 of the strut with V-shaped teeth 10 which are 90 adapted to dig into'or engage the ground or the cement over Which the door swings the device, in such instance, being arranged on the inner face of the .door and being .adapted to be used to hold the door from y swinging shut. The door in this instance,

. of course, is an outwardly opening door.

The end 9 of the strut 1s curved symmetrically in the direction of swinging motion of the strut and is provided with a plurality of the teeth 10. This form is particularly useful Ifor enga ement with a cement floor as the strut wi l engage with the floor and as the door starts to swing the strut will tend to swing slightly toward the door and cause the teeth to engage the cement with great force. i

A particularly advantageous feature of this form of strut lies in the symmetrical formation of its free end whereby which U0 ever way it is assembled with the base it will present teeth to the floor when dropped to engaging position.

For some purposes,l it is desirable to widen the engaging surface of the strut with the floor and in Figures 6 and 7 I have shown the strut as provided with a shoe 12 which is pivotally mounted on the lower end of the strut 3 by means of a rivet 13. The shoe as best shownin Figure, 7 has a contacting surface which is muchwider than the strut bar and is provided with transverse teeth 14 for engagement with the floor. The shoe 12 can rotate to some extent on the bar lbut is prevented from rotation out of engagement with the floor by means of the engagement gf the shoe with the lower corner 15 of the `In Figure 8 I have shown a shoe 16 similar to the shoe 12 but provided with a rubber pad 17 for contact with the floor and the rubber pad is provided with transverse ridges 18 similar to the teeth 14 on the shoe 12. Iind that this rubber padded end on the strut is useful on the device when applied to doors swinging over finished iioors.

I do not herein specifically claim the base with the two pairs of struck up lugs, such being claimed in my companion application Serial Number 587,333. I

As many modificationsof my invention will readily suggest themselves to one skilled in the art, I do not limit or confine my invention to the specific details of construction herein shown and described.

I claim:

1. In a device of the kind described, a

strut adapted to be pivotally one end to swing up and down, the free end of the strut provided with a yielding gripping surface curved in the direction of swingingmovement of the strut and said surface provided with transversely extending V-sha-ped ribs.

2. In a device of the kind described,` a flat strut adapted to be pivoted at one end to swing u and down edgewise, a shoe on the free en of the strut, the shoe provided with a gripping surface extending beyond the flat faces of the strut, and curved in the direction of the swinging movement of the strut, as and for the purpose specified.

3. In a door stop, a sheet metal base adapted to be secured to a door, the sheet metal base provided with two pairs of struck-up lugs, one pair above the other, a flat metal bar strut adapted to be pivoted between the lower pair of lugs to freely swing up and down, the upper pair of lugs being formed to ermit the body of the strut to be forced etween them and to be engaged by a yielding pressure for holding the strut in an inoperative position, thefree end of the strut being curved and formed with V-shaped teeth for engagement with a roadway, said free end being symmetrical in relation to its edges so as to be capable of presenting the engaging teeth to the roadwa of iihe strut and base.
